Question

When heat is supplied to a solid substance: a) the kinetic energy of the particles increases. b) the potential energy of the particles increases. c) the potential energy of the particles decreases d) the potential energy of the particles decreases

Answer 1

Answer:

the answer is A

Explanation:

The heat energy supplied to the solid increases the kinetic energy of the molecules, as a result they start vibrating and transfer the energy to adjacent molecules and this goes on. If the heat supplied is sufficient it may change state of substance from solid to liquid or gas.

Answer 2

Answer:

(A)the kinetic energy of the particles increases

Explanation:

It is because when heat is supplied the bond between solid particles get dissociated and therefore the space between particles is increased hence they can move freely so the kinetic energy iss increased
